face zones/sets in OpenFOAM-1.6-ext
1 Attachment(s)
I was looking into switching to 1.6-ext (I currently use 1.5-dev) and I commonly use the GGI capabilities for turbomachinery applications so I started by trying to run the 2D centrifugal pump case from SIG Turbo validation cases: http://openfoamwiki.net/index.php/Si...vaned_diffuser
This case runs without issue in 1.5-dev but not so in 1.6-ext. There seems to be some differences in how 1.6-ext builds face zones (or it could be the face sets - I'm not 100% sure what the root cause is). I can run the makeMesh script Ok but when I run checkMesh to make sure the rotor, stator, GGI interfaces and cell zones were built properly I get an error. Here's the error reported from checkMesh (and I've attached a log file for completeness): Code:
***FaceZone GGI_EXT_ZONE is not correctly synchronised across coupled boundaries. (coupled faces both present in set but with opposite flipmap) Unless something changed about how face sets and zones are created from 1.5-dev to 1.6-ext, this appears to be a bug. If someone knows better feel free to enlighten me. I would have logged this bug through the bug tracker on extend-project.de but it doesn't seem to be currently working. |
I was told there is in fact no error and to ignore checkMesh's warning (the error is actually in the error reporting). I haven't run it yet to verify it but it should run Ok.
